Originally manufactured by Hurtbetz, the Round-Up is a very common ride that can be found across the country in nearly 100 locations. The ride often appears with "Super" added to the front of its name. Since debuting in 1954, it has gradually grown in size, with the example above being perhaps the largest version built.
These pictures show Idlewild's ride, which has been missing in action since 2018 because of it being in the floodplain of the Loyalhanna Creek. The park says they are going to bring it back this year, but I'll believe it when I see it! Here's the site's current state:
Ride Experience
Riders step onto an inclined platform and secure themselves in an individual compartment along the ride's perimeter in a standing position. The Round-Up has a simple chain-link restraint due to the strong centripetal force that is put on riders. The ride lifts up a bit beyond a 45-degree angle, and the entire circle spins, pinning riders against the wall. This crests a highly disorienting effect, and many riders have been known to get sick while on a Round-Up. After a time whirling and twirling in the air, the ride comes back to its level position.
